Novel lift well

Abstract

The invention relates to a novel lift well. The novel lift well comprises polyhedral upright columns, a base plate, a top plate, a lift car frame and a counterweight housing. The lift car frame comprises an upper beam, lift car upright columns and a base beam. Guide shoes are arranged on the lift car upright columns. The counterweight housing comprises counterweight beams and counterweight upright columns. At least four hollow polyhedral upright columns are arranged in the lift well. Column piles are further arranged in the lift well and connected to the two end faces of the polyhedral upright columns in a threaded mode. The base plate and the top plate are placed at the two ends of the polyhedral upright columns correspondingly and connected with the column piles in a threaded mode. The polyhedral upright columns are arranged to be used in cooperation with the guide shoes arranged on a lift car through rectangular protrusions arranged on the polyhedral upright columns so that car guide rails can be formed. Further, the four-guide-rail structure is adopted, each polyhedral upright column is matched with the two guide shoes arranged at the corresponding apex angle of the lift car, the phenomenon of severe abrasion of the guide shoes caused by lift car eccentric loading is eliminated, and therefore, the stability of lift operation is enhanced, installation cost is lowered, installation precision is improved, and lift space occupation is reduced at the same time.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to a novel elevator shaft. technical background [0002] With the improvement of people's living standards, the demand for elevators in people's daily life continues to increase. In view of the lack of supporting facilities in the early apartment buildings, elevators cannot be directly installed inside the apartment. When in use, the elevator needs to be installed outdoors through civil engineering or existing steel parts to build the shaft. At the same time, car guide rails and counterweights need to be installed in the shaft. guide rails, so a large hoistway area is required; and the installation process of the existing elevator shaft is cumbersome, a large number of processes need to be completed on site, the construction period is long, the installation cost is high, and the overall accuracy of welding is not high, which affects Effect of use; In addition, the existing car fr...

In view of the lack of supporting facilities in the early apartment buildings, elevators cannot be directly installed inside the apartment. When in use, the elevator needs to be installed outdoors through civil engineering or existing steel parts to build the shaft. At the same time, car guide rails and counterweights need to be installed in the shaft. guide rails, so a large hoistway area is required; and the installation process of the existing elevator shaft is cumbersome, a large number of processes need to be completed on site, the construction period is long, the installation cost is high, and the overall accuracy of welding is not high, which affects Effect of use; In addition, the existing car frames are equipped with uprights on both sides near the middle, and the guide shoes on the uprights are used in conjunction with the car guide rails. When the car is unbalanced, the force on one side of the guide shoes will be increased. The wear of the guide shoes increases and generates noise, which affects the smoothness of the elevator operation and increases energy consumption
